NGC 6153 is a planetary nebula in the southern constellation Scorpius. It was discovered in 1883 by English astronomer Ralph Copeland. This nebula has been observed using telescopes with apertures as small as 80 mm (3.1 in), but a rich Milky Way background can make it difficult to find. It has an apparent visual magnitude of 10.6 and spans an angular diameter of 30″.
